Well, as has been said, if you post a for sale thread on here you know you will have the "go to a good home and will be appreciated" thing down - while many will love you forever for selling some of these things on here, the only issue you run into is that prices have to be listed so you can't rely on a bidding market to price them (good or bad) for you - but we DO have a thread you can ask what people think things are worth so that might help you not undersell yourself. You also save with ebay fees on here (but still have PayPal fees theoretically).
Whatever doesn't sell around here you could either try lowering your prices or listing on eBay to clear out your inventory.
Hope that helps! And welcome to the community (even if you don't plan on staying awhile).
Oh yeah - you don't happen to have a halo reach briefcase press kit do you?
